The reasons for the detonation of the distribution box are as follows:
1. The distribution box is kept in overload work for a long time, which is easy to cause;
2. The fuse of the fuse in the distribution box is not used in accordance with the regulations;
3. Sparks and arcs occurred when the switch operation of the distribution box or the fuse was blown;
4. The wiring of the distribution box is not very strong in contact with electrical appliances, meters, etc., and the contact resistance is too large.
5. The switches, fuses, and meters used do not meet the actual capacity requirements of the distribution box.
Another point is that the distribution box has not been cleaned for a long time, resulting in too much combustible dust inside, and the distribution box cannot perform good heat dissipation.
